WASHINGTON - President-elect Donald Trump has named Susie Wiles, the manager of his victorious campaign, as his White House chief of staff, the first woman to ever hold the influential role.

Wiles is widely credited within and outside Trump’s inner circle for running what was, by far, his most disciplined and well-executed campaign, and was seen as the leading contender for the position. She largely avoided the spotlight, even refusing to take the mic to speak as Trump celebrated his victory early Wednesday morning.

She was able to do what few others have been able to: help control Trump’s worst impulses — not by chiding him or lecturing, but by earning his respect and showing him that he was better off when he followed her advice than flouted it.

“Susie is tough, smart, innovative, and is universally admired and respected. Susie will continue to work tirelessly to Make America Great Again," Trump said in a statement. "It is a well deserved honor to have Susie as the first-ever female Chief of Staff in United States history. I have no doubt that she will make our country proud.”

Trump went through four chiefs of staff — including one who served in an acting capacity for a year — during his first administration, part of record-setting personnel churn in his administration.

Successful chiefs of staff serves as the president’s confidant, help execute a president’s agenda and balance competing political and policy priorities. They also tend to serve as a gatekeeper, helping determine whom the president spends their time and whom they speak to — an effort Trump chafed under inside the White House.

The chief of staff is “absolutely critical to an effective White House,” said Chris Whipple, whose book “The Gatekeepers” details how the White House chief of staff role shaped and defines a presidency. “At the end of the day the most important thing is telling the president what he doesn’t want to hear."

Wiles is a longtime Florida-based Republican strategist who ran Trump’s campaign in the state in 2016 and 2020. Before that, she ran Rick Scott’s 2010 campaign for Florida governor and briefly served as the manager of former Utah Gov. Jon Huntsman’s 2012 presidential campaign.

Chris LaCivita, who along with Wiles served as a co-manager of the campaign, posted on X, “So Happy and proud of one of the fiercest and most loyal warriors i’ve ever had the pleasure of working with !!!”
